Multilocus VNTR analysis-ompA typing of Chlamydia trachomatis isolates in Tehran, Iran.

Introduction: This study is the first to describe the genetic diversity of C. trachomatis strains derived from patients with signs and symptoms of genitourinary infections admitted to Tehran health centers and hospitals using the high-resolution genotyping method, multilocus variable-number tandem-repeat analysis with ompA sequencing (MLVA)-ompA.

Methods: One hundred and sixty-seven urogenital specimens were collected from October 2019 to July 2020.

Associations between climatic parameters and the human salmonellosis in Yazd province, Iran.

Salmonella is one of the most common causes of foodborne disease outbreaks in developing countries. Climatic factors such as temperature, rainfall, and relative humidity can directly increase the growth and spread of these pathogens. Therefore, the aim of this study was to investigate long-term temporal trends and seasonal patterns of Salmonella infections as well as evaluating the effects of demographic and climatic factors on the infection incidence in Yazd province, Iran during 2012-2015.

First Detection and Characterization of Macrolide-Resistant from People with Community-Acquired Pneumonia in Iran.

Increasing macrolide resistance of strains is becoming a public health concern worldwide. Nevertheless, no comprehensive genomic background of circulating isolates is available in our region. We aimed to study the genetic diversity of this microorganism using the multiple-locus variable-number tandem-repeat analysis method and to investigate the relationships between MLVA types and macrolide susceptibility profiles of the isolates.

Foodborne Disease Outbreaks Related to Environmental Conditions in Yazd Province, Iran.

Background: The aim of this study was to assess associations of foodborne outbreaks with environmental factors in various regions of Yazd Province, Iran, 2012-2016.

Methods: The public health surveillance data were used for one period of five years reported foodborne disease outbreaks in various regions of the Province. Multilevel regression statistical method was used to analyze associations of climatic and demographic variables with outbreaks.

CbpM and CbpG of Streptococcus Pneumoniae Elicit a High Protection in Mice Challenged with a Serotype 19F Pneumococcus.

Among many pneumococcal antigens, choline-binding proteins (CPBs) display a high immunogenicity in animal models. This study aims to determine the immunogenicity of CbpM, CbpG and CbpL proteins of Streptococcus pneumoniae in a mice model. The genes were cloned into pET21a expression vector and the recombinant proteins were produced.

Molecular epidemiology and genetic characterization of Shigella in pediatric patients in Iran.

Infection with Shigella is considered a major cause of morbidity and mortality in children with diarrhea in developing countries, especially in Iran. Due to the importance of country-level epidemiological data, molecular characterization of genetic determinants of Shigella spp. is a necessity.

High frequency of among patients with atypical pneumonia in Tehran, Iran.

Introduction: is a major cause of atypical community-acquired pneumonia (CAP) with a prevalence range of 15-20% and up to 40% in adults and children, respectively. In Iran, the recorded frequency ranges between 1-6.15%.

Biofilm formation and antimicrobial resistance in methicillin-resistant Staphylococcus aureus isolated from burn patients, Iran.

Introduction: Burns are the most serious forms of trauma and a major cause of mortality worldwide. Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most common pathogens of burn wound infections; treatment has faced serious problems due to antibiotic resistance in these strains. Biofilm formation, which increases antibiotic resistance capabilities and is considered to be a virulence factor, also causes treatment failure and recurrent staphylococcal infections in burn patients.
